IBM Edge 2014 Call for Speakers is Open!
Do you have a story that you want to tell? IBM is giving you a chance to tell the world how you are making your business or the industry better. This year we are focused on four areas: Social, Mobile, Analytics and Cloud. These subjects will be the cornerstone of the conference and sessions will be selected on how your business was changed by them.
We want attendees to better understand why its important to move Infrastructure from an afterthought to a strategic mission critical choice, and want presenters to discuss how IBM infrastructure is a unique enabler for growth and innovation. Ideally, a speaker can incorporate how the company's strategic and forward thinking decisions about infrastructure have directly impacted the enterprise's ability to respond effectively to new opportunities, challenges and the demands of growth and innovation. We look forward to inviting customers to speak and will pay for their conference fee as a token of thanks.
If you are interested in speaking and attending Edge, please email me back with some details below and I will get your information into the database for the selection committee.
Please send me your name, company and contact information and the specifics you might include in your project/story including:
What IBM solution components? what is your implementation?
What terms of the decision process did you go through and the impact to your business?
Will you be comfortable including some business impact context?
Is there a tie-in with Cloud, Analytics, Mobile or Social type of workload ?
How has IBM technology helped you run the business better?
If you are interested, please let me know by March 12 as the deadline is next Friday for submissions.
IBM Storwize® V7000 Unified stores up to five times more unstructured data in the same space with integrated Real-time Compression
IBM Storwize® V7000 Unified stores up to five times more unstructured data in the same space with integrated Real-time Compression
Today IBM announced the enhancement of compressing not only block data on the V7000 but also now it includes the file data on the V7000 Unified. The V7000 was first set up with compression back in the summer with a big announcement surrounding “Smarter Storage”. This optimization was the same code and engine that was purchased from a company named Storwize a few years ago.
IBM initially kept the compression appliance that Storwize was first known for in the market. Using LZ compression with a RACE (Random Access Compression Engine) providing an optimized real-time compression without performance degradation. Thus slowing down data growth and reducing the amount of storage to be managed, powered and cooled.
The compression does not require the compression or decompression of entire files to access the data block. The engine will compress and decompress the relevant data blocks “on the fly”. As data is written the RACE engine compresses the data into a smaller chunk and its 100% transparent for systems, storage and applications.
The V7000 Unified can now deliver a larger compressed platform than any other mid-range platform. With compression percentages around 75%, a system that was maxed out at 2.8 PB (960 drives x 3TB each) can now see the system handle up to 5 PB of storage.
Each V7000 Unified with code base 6.4 has the option of turning on a 45 day trial of the compression software. After setting the license to “45” then you can add new compressed volumes on the system. You can also compress data on virtualized storage arrays.
Compression has been part of NAS for a very long time. We have seen compression of files from jpeg to office documents. But the best part is the end user will never have to worry about which files needed to zipped or compressed. Everything that comes through the V700 Unified can be compressed in line before it writes the data to disks.
A couple of other improvements that IBM announced were the addition of a integrated LDAP server to V7000 Unified. This now allows customers to use both local authentication and external authentication servers to allow access to data. Another feature was the ability to upgrade a V7000 to a V7000 Unified in the field. If you currently own a V7000 but need to add file access to the system, IBM will sell you the two file modules and corresponding software to upgrade you system. Now mind you there is a list of requirements that will need to be met so check with your local storage engineer for more information. And finally we now have support for a 4 way cluster on V7000 unified. This allows for more disks to be provisioned and can compete with some of the other mid-range storage platforms in the market.
This all together makes a nice round of improvements that will make life easier for IBM customers. As the V7000 platform matures it looks like IBM is putting their money where their mouth is and making storage smarter and more efficient. More to come on this platform as I suspect we will see bigger things down the road.
Do you expect more out of your storage? IBM thinks you should and is putting their money where their mouth is. In the past it has gone under different names like STG University and Storage Symposium, but now IBM has revamped its premier storage conference. The big announcement came today with much fanfare that included a new website, some videos and bunch of hype on twitter. A three part conference for executives, gear heads and business partners there is something for everyone. But what will be different tham years in the past? I think IBM looked around how other vendors use conferences to help pump up its customer base (VMWorld, EMCwhatever) and decided to put some hype in the conference.
Think of this as a great place to go and network, learn and have a good time. The conference will be in Orlando and there will be tons of time to sit in class rooms and learn about the latest technologies but there will be sessions where IBM will be pulling in our top execs and analysts to tell you where IBM is going in the storage world.
The Executive Edge will feature different speakers from Jeff Jonas, Aviad Offer and IT Finance expert Calvin Braunstein. This track will take executives through new announcements, deep dives on technical platforms, one on one sessions with IBM Execs and some great entertainment. This is a new feature of the conference as in the past it was more geared towards the technical teams.
Of course the Executive Edge will be limited so talk to your local storage sales person to get a chance to be a part of this special event. There will be time to bring in your team and have special sessions and round tables with the IBM engineers who can help you find your way down this path of crazy storage growth. And there is a golf course on site which I have heard is very nice. Bring your clubs or rent them, I am sure there will be plenty of us out there so find a partner and have a good time.
More importantly IBM is making the effort to step up the event and have it on par with the other IBM conferences like Pulse. The technical portion will have over 250 sessions on storage related topics. You will also get road-map information from the product teams as well as a chance to become a certified technician. One area that has been expanding is our hands on labs and this year we will have the biggest one yet. You will be able to come in to the labs and actually see our storage systems and have a chance to 'test drive' them.
Early bird registration is open now
and you can sign up today. The conference will be in sunny Orlando
Florida at the Waldorf Astoria and Hilton Orlando at Bonnet Creek. The
event starts on June 4th and runs to the 8th. You can follow the
conference on twitter @IBMEdge and use the hashtag #ibmedge For the conference website go here
I look forward to seeing you in June.

My father is a retired teacher but loves to work with his hands. I can remember very early on in my up bringing, him teaching me that it is good to measure twice and cut once. Whether it was building a deck or just a bird house the point was it took more time to cut something wrong and then has to re-cut the board shorter or even wastes the old board and cut a whole new one.
When I was preparing for this article I remember having to learn that lesson the hard way and how much effort really is put into that second cut. The problem in the storage industry is the misaligned partitions from a move of a 512 byte sector to a new 4096 byte sector. This has to be one of the bigger performance issues with virtualized systems and new storage.
Disk drives in the past had a limit on the number of sectors to 512 bytes. This was ok when you had a 315 MB drive because the number of 512 byte blocks was not nearly as large as what is in a 3 TB drive of today’s’ systems. Newer versions of Windows and Linux will transfer the 4096 data block that match the native hard disk drive sector size. But during migrations even new systems can have an issue.
There is also something called 512 byte sector emulation which is where a 4k sector on the hard disk is remapped to 8 512 byte sectors. Each read and write would be done in eight 512 byte sectors.
When the older OS is created or migrated, it may or may not align the first block in the eight block group with the beginning of the 4k sector. This causes misalignment of a one block segment. As the reads and writes are laid down on the disks the misalignment of the logical sectors from the physical sectors mean the 8 512 byte blocks now occupy 2 4k sectors.
This now forces the disk to perform an additional read and/or write to two physical 4k sectors. It has been documented that sector misalignment can cause a reduction in write performance of at least 30% for a 7200 RPM hard drive.
This issue is only magnified when adding other file systems on top of this misalignment. When using a hyper visor like VMWare or Hyper-V, the virtual image can be misaligned and cause even further performance degradation.
There are hundreds of articles and blogs written on how to check for you disk alignment. A simple Google search of the words “disk sector alignment” and you will find this has been a very popular topic. Different applications will have different ways of checking and possibly realigning the sectors.
One application that can help you identify and fix these is a tool called the Pargon Alignment tool. This tool is easy to use and will automatically determine if a drive’s partitions are misaligned. If there is misalignment the utility then properly realigns the existing partitions including boot partitions to the 4k sector boundaries.
I came across this tool when looking for something to help N series customers who have misalignment issues in virtual systems. One of the biggest things I saw as an advantage was this tool can align partitions while the OS is running and does not require the snapshots to be removed. It also can align multiple VMDKs within a single virtual machine.
For more information on this tool and alignment check out the Paragon Software Group website.
In the end, your alignment will effect how much disk space you have, how much you can dedupe and the overall performance of your storage system. It pays to check this before you start having issues and if you are already seeing problems I hope this can help.
Now available is the IBM System Storage N series with VMware vSphere
Redbooks are a great way of learning a new technology or a reference for configuration. I have used them for years not just in storage but for X series servers and for software like TSM. The people that write the books spend a great deal of time putting them together and I believe most of them are written by volunteers.
This is the third edition of this Redbook and if you have read this before here are some of the changes:
-Latest N series model and feature information.
-Updated the IBM Redbook to reflect VMware vSphere 4.1 environments
-Information for Virtual Storage Console 2.x has been added
This book on N series and VMware goes through the introduction of both the N series systems and VMware vSphere. There are sections on installing the systems, deploying the LUNs and recovery. After going through this Redbook, you will have a better understanding of a complete and protected VMware system. If you need help with how to size your hardware there is a section for you. If you are looking to test how to run VMs over NFS, its in there too!
One of the biggest issues with virtual systems is making sure you have proper alignment between the system block and the storage array. This will negatively impact the system by a factor of 2 in most random reads/writes as two blocks will be required for one request. To avoid this costly mistake or to correct VMs you have already setup a section in the book called Partition alignment walks you through the entire process of correctly setting the alignment or fixing the older systems correctly.
Another area that I will point out is the use of deduplication, compression and cloning to drive the efficiency of the storage higher. These software features allow customers to store more systems on the storage array than if they used traditional hard drives. Also there is how to use snapshots for cloning, mirrors for Site Recovery Manager and long term storage aka Snapvaults. At the end of the book are some examples of scripts one might use for snapshots in hot backup modes.
Whether you are a seasoned veteran or newbie to the VMware scene, there is a great guide that will help you from start to finish setting up your vSphere environment. The information is there, use the search feature or sit down on a Friday with a high-lighter, which ever fits your style and learn a little about using a N series system with VMware.

Storwize V7000 Unified, A marriage of SAN and NAS
Storwize V7000 and the IBM NAS software were married Wednesday, October 12, 2012 at midnight at IBM Storage chapel in San Jose, California. The Reverend Rod Adkins officiated. Following the ceremony, the bride’s parents hosted a reception at the Almaden Research Center.
The bride comes from the NAS family who were in attendance. She also has ties with the Tivoli and GPFS families deep within the storage community. There were family members from the X series family who were at the ceremony.
The groom comes from a long line of storage products. XiV, DS8800 and SVC were all part of the festivities and supported the groom throughout entire day.
The couple will honeymoon Redwood City, California with a visit to the Storage Performance Council.
After long anticipation, IBM is now in the unified storage market with the introduction of the Storwize V7000 Unified (SV7kU?). The system stands as small as 6U of rack space and can flex up to four clustered systems (via RPQ) supporting internal SAS, SATA or virtualized external disk from other vendors.
The V7000 Unified is a midrange disk system that will allow new V7000 or existing V7000 customers the ability to integrate their NAS workload into the system. Using the standard V7000 shelf, IBM has added two 3650m3 servers with the IBM NAS software stack to complete a unified architecture.
A new GUI that ingrates the NAS portion of the software is now available that will combine management for both technologies with a few mouse clicks. Setup of the system stays the same with the simplified USB key approach. Customers have reported that between the USB key installation and the wizard driven alerts, the V7000 has been one of the easiest systems to install and configure. IBM decided to keep these features in the enhanced GUI.
V7000 Unified will support NFS/CIFS/FTP/HTTPs/SCP protocols in addition to block functions FCP and iSCSI. It will also support file replication and file level snapshots for business continuity in addition to existing block functions.
Another function in the V7000 Unified that will help customers is the introduction of the IBM Active Cloud Engine. What is it? Think of it as a very smart, very fast robot – that never sleeps – keeping your cloud storage neat, tidy and running smoothly. Think Rosie the robot from The Jetsons.
This engine is a policy driven engine that will help improve the storage efficiency by automatically placing, moving and deleting files to the appropriate storage. The efficiency gain comes from storing the files where they should be with out an administrator manually moving them. As data is gets older, the engine can move the file to another location where the price per TB is less and even delete the file if necessary.
The movement is done seamlessly and the end user does not have any idea their data has moved. Another aspect of the engine is identifying files for backups or replication to a DR location. As the data ages, the data continues the life cycle through the data center without storage administrators intervention.
Data can be moved from internal disk to external virtualized disk and even to tape. The diagram below shows the movement from file creation to 180 days old and off to deduped tape.
The policy can be created from a wizard in the V7000 Unified GUI by creating thresholds and start times. Customers can also exclude certain files by different file attributes like size or last accessed. For the more advanced customer, an edit feature of the policy is allowed.
Another question people are asking is about the relationship with Netapp and how will this product effect the N series product line. IBM is expanding the midrange storage portfolio by offering both the new V7000 Unified along with our N series products to focus on different client needs.
N series continues to be IBM’s offering focused on clients who have a primary need for NAS optimized (file) workloads. Existing N series clients with growing data requirements will continue to require additional N series disk drives, expansion units, and new systems to meet their needs.
IBM Storwize V7000 Unified will particularly appeal to clients who have a primary need for storage to support block optimized workloads with additional needs to consolidate file workloads for greater efficiency (unified storage). Storwize V7000 Unified is also targeted to clients that can benefit from the unique capabilities of IBM Active Cloud Engine or to clients that already are using Storwize V7000 or SONAS.
Just like in real life, we have seen other marriages come and go but this one seems to be different. The V7000 Unified is using the best of the storage portfolio and bringing value to the customer. IBM is also leveraging the investments made over 10 years of innovation; Virtualization, Easy Tier, Simplified GUI, Active Cloud Engine and is producing a product that will accomplish the lowering total cost of ownership.
As goes with the tradition of the bride to have good-luck:
“Something old, something new, something borrowed,
something blue, and a silver sixpence in her shoe."
(You can find this poem in Leslie Jones' book "Happy is the Bride the Sun Shines On."). We find the IBM version of this offering good luck with the following:
Something Old: 4,500 V7000 systems sold last year
Something New: Active Cloud Engine
Something Borrowed: Storage Virtualization
Something Blue: Storwize V7000 Unified, a true IBM organic product
I am still looking for the sixpence but feel free to mail us one and we will attach it to the bezel of each controller.

I just read the blogs from Chris Mellor from the Register and Tom Trainer Network Computing and thought how insightful are these two outsiders about the inner workings of IBM.
First off, yes IBM is no longer selling the DCS9900, a DDN OEM rebranded system in the very large IBM storage portfolio. There is no question that this product is no longer available after the October 15 date.
Second, the DCS 3700 is already part of our portfolio and is now an OEM box from Netapp/Engenio/LSI. The density of this system is the same as the DCS 9900 and makes sense to use the DCS 3700 as a replacement for the DCS9900.
Third, Tom’s blog about SONAS being a monolithic NAS storage is very skewed. SONAS is a very flexible in the way we can scale both storage and the throughput with out affecting either variable. Most “scale out” systems you have to scale both in order to keep up with demand. SONAS uses some of the best technology on the market with a huge amount of throughput.
His statement about IBM dropping DDN from SONAS is un-true and goes to show how much research Tom put into writing this blog. I am sure Tom is looking out to write a non-biased blog for Network Computing but maybe those days at HDS are still making a big influence in his ability to look at announcement letter and make a extrapolations about other products.
Finally, If HDS thought BlueArc was so great, why didn’t they buy them back when they could have gotten the company for a better deal? Has the product changed THAT much since 2006? I wish HDS only the best for dealing with the transition and getting that product under the HDS umbrella.
If you do your homework and base your assumptions on facts instead of conjecture, you will find SONAS is a solid platform in the enterprise NAS market. SONAS has proven it can be the market leader with a low cost to performance ratio and will only get better as time goes on.

Last week at the IBM Technical Conference I was able to spend some time with a couple of friends discussing technology. It is always interesting to hear their take on where the storage market is going and what lays ahead in the future. As my Netapp pal and I were chatting about the messaging around unified architecture, we both noted that unified to one perceptive is disjointed to another.
IBM and Netapp have been using the term unified for its NAS/SAN device for about 5 years now. The idea is to share a common code base on the same hardware to increase functionality and usability of that storage. Other vendors have gone similar routes using multiple code bases and/or hardware but I see that as a NAS gateway in front of SAN storage system.
This has been very successful in data centers both large and small. But the idea of how we manage storage is changing. Virtualization is changing the idea of how and even where our data may be stored. The term cloud is something of a marketing term but I like the term Storage Utility better. Utility companies such as electric, water, sewer and even cable provide a product to its consumers and storage utility vendors could do the same.
Most people are not concerned about process companies take to make water drinkable or how electricity is generated as long as it is safe, reliable and easy for them to consume. Storage as a Utility is no different, it is only when the storage is offline or hacked in by outsiders the consumers are concerned. There are laws that govern utilities and the FTC has put some privacy laws together to help consumers but I believe we can take it a little further (a blog for another time).
As our data is changing from traditional spinning drives in our data center to a storage utility, we will need some type of bridge that will ease the pain of transition. The main reason people do not adapt new technology is because the transition is often too painful and the benefit of new technology is less than the need to move. Whether it is a software package that helps move data or a hardware device, it will have to give access to both file based data and object based data. This will allow for users to read the files as needed no matter what their connectivity or location. It could also be used to help drive efficiencies up buy allowing data to move from file based (high cost) to object based (lower cost) environments.
Today there are some vendors who have early versions of this type of unified solution. They are bridging the gap between what we have today in private data centers and the future of public utility storage. This is very early in the transition but with this type of technology, we will be able to adapt and provide a better way of storing data. Will it still be called a unified solution? Only the marketing people can tell us that.
I was just thinking the other day that I really need to write an article for my blog about the upcoming releases. When I opened the page it said I had not written anything since May of this year. Time really flies when you are having fun, so they say.
IBM just released a new XiV system dubbed the Gen 3. Generation 1 of course was built by the XiV company before IBM purchased them, then came Gen2 shortly there after. As you expect the system has to keep up with customer demands and technology refreshes but some thing very unique caught my eye. The performance with this system will be heads and shoulders above the competition.
Nehalem micro-architecture now makes up the heart of the processing power within the grid with tons more cache to boot. There is a change in the inter-connectivity from Ethernet to Infiband. I can’t wait to see the new SPC2 numbers when they are published.
I suspect with the introduction of more cache (via SSD) and the switch over to near-line SAS drives is only going to help increase performance from gen2 to a gen3 system. The self tuning/healing, tierless storage is still at the heart of the system and still redefines how storage is done today.
There are plenty of blogs and articles on the specifics of the release but here is the IBM announcement page http://www-03.ibm.com/systems/storage/news/announcement/big-data-20110712.html

May 9th has been a target on my calendar for some time now. Inside of IBM, we have been waiting for this day to come so we could talk about the new things being released in the storage platform. It almost feels like Christmas morning with a bunch of new presents under the tree. Each gift has inside something that is either really cool or something very useful. The only difference is your Aunt Matilda and her little dog is not coming over for brunch.
Under the IBM tree today is a slew of presents for almost the entire storage platform. I will concentrate on just the IBM NAS ones but if you are interested in knowing what is going on elsewhere, you can find more information at the main website.
SONAS must have been a good boy because there are plenty of gifts for him under the tree this morning. Not only did he find presents under the tree but there were a few little things in his stocking. Here is what Santa brought:
This SONAS release is labeled R1.2 and can be obtained by contacting the technical advisor assigned to you.
Santa was also at the N series house and dropped off a few gifts. A new N6270 to replace the N6070. This new system is in line with the N6200 series with larger amounts of RAM and processors. Just like the smaller N6240, there is an expansion controller where customers can add more PCI control cards like HBAs, 10GbE or even FCoE. A new disk shelf was also released which uses the smaller 2.5 inch drives with improved back end performance.
And over at the Real Time Compression house they got new support for EMC Celerra.
Over all a very busy time of year for IBM (and Santa) as these were just a fraction of the Storage announcements today. Also today is the IBM Storage Executive Summit in New York City. My friend and fellow blogger Tony Pearson is covering this great event and will be updating his blog and twitter feed. If you were not able to make it to NYC for the event, feel free to tweet him your questions @az990tony You can also send questions to our IBM Storage feed at @ibmstorage
This week, I am at SNW in San Jose, CA. If you have never heard of the conference, its all about storage and networking and pulls in all of the big vendors to put on labs, lectures and a vendor hall. People come from all over the world to this event to learn what is new and how to do things better.
One thing that I love doing at these events is talking to customers and potential customers about IBM storage technology solutions. Often we find the conversations do not talk about products as much as the technology in them that fix some sort of issue in the data center. I think this is best seen when you come in to the IBM booth. There is no hardware to see blinking lights or yank cables. We have something better, people who know the solutions to your issues.
If you ask any of the IBMers that work these events, they always say it’s a love hate relationship. The hours are long and you stand on feet for 4-8 hrs. The best part is talking about IBM solutions and finding out what people are doing in the field. This is the best way to help drive innovation, listening to the customer. IBM has programs that send our developers into the field to listen to customers and this is just one example of that program.
Another event at SNW this year was a gathering of the storage social media moguls. This is a non-vendor specific event and is open to everyone. It is associated with a certain hash tag of #storagebeers and they have been going on all over the world. Last night was the largest storagebeers to date and it was a whos who of this community. But what was better than meeting the people that you see on twitter or those who write blogs, was the idea of putting all of the vendor fighting behind us and just a group of people who work in the storage industry talking about whatever was on their mind. If you find yourself at an event like SNW or VMWorld, check to see if there is a #storagebeers and go back and meet some really cool people.
If you are at SNW and want to come by for a chat, you will find me at the IBM Booth today between 11am and 3pm. I would love to spend some time learning about what you are doing in the data center.

My friend and colleague Ian Wright has put together an awesome You Tube video of the V7000 with the Flash Copy manager software. Ian has made several videos of the V7000 including a tour of the GUI, how to do things and now this. Ian says in an email to me earlier: "The video starts out with a restore of an accidentally deleted email (but not a restore of the spam that was deleted) and goes on to show recovering an accidentally deleted database. Both are actions that I think should resonate with customers using these applications."
I thought this was an awesome example of the V7000 and the Rapid Application Storage Solution that was release a few months back. Please take a few minutes to go through the video and give Ian some feedback.
Day 1: Today, IBM has massed the troops together to learn more about the SONAS product and how the product will look in the near and far future. There is a ton of information they are dumping that I need time to just process it all. Its also nice to meet people from all around the world that have the same mission as I do. I hope to get some interviews tomorrow as well as listening to Sven Ohme talk about performance of the box.
This video is shot in front of the first hard drive, ever. What a testimonial to the IBM innovation. The first words written are..... you gotta watch to find out.
I am headed out west to learn more about SONAS and the future of the product. I think there will be lots of good information that I will try to share with you. If you have any question that you want to ask a SONAS developer, let me know as they will all be there!
Today IBM is releasing two new N6200 systems that will be a huge improvement over the existing N6000 systems. The two new systems will show a bump in capacity and performance and more flexibility. For a very crowded midrange market this new N series product set will bridge the gap between entry level and enterprise class systems
The first thing that stands out to me is the footprint of the new system. The older N6000 has a 6 U requirement for an HA pair. The new N6200 is half the size, only occupying 3U for the two HA pair, or a single node with a I/O expansion module, providing an additional four PCI-e cards. Another configuration is two controllers with two expansion modules in a total space of 6U (equal of the older N6000 systems) but with a total of 12 PCI-e slots (vs 8 on the older N6000).
We will recommend using the two slots built into the controller for high performance 10GbE and / or 8 Gb PC adapters. The additional expansion slots in the expansion module can be used for Flash Cache and other connectivity for disks.
The on-board hardware is getting an face lift as well. While the new system sports a 10GbE port this is used mainly for the interconnect and nothing else. This was one of the disappointments I have with this systems, but understand this is how Netapp will accomplish scale out clustering.
FC ports were kept at 4 Gbps but there is two new SAS ports with matching ACP (alternate control path) ports used for off loading some of the traffic from the data path.
One of the unsung updates was in the NVRAM. Instead of using the same memory in the past, we now see an improvement of the memory by using something called Asynchronous DRAM Refresh (ADR). This is a new self-refresh mode in the Intel chipset that allows a portion of the main memory to be backed by an on-board battery. This gives the NVRAM the same high bandwidth as main memory and also simplifies the design of the motherboard.
This gives the new N6200 systems a bump in performance along with the introduction of the new Intel processors. The SPECsfs benchmark on the highest N6200 system showed 101,183 ops at 1.66ms ORT compared to the N6060 showing 60,507 ops and 1.58ms ORT, an improvement of about 70% in SFS throughput.
IBM is introducing the IBM System Storage N6210 Series and the IBM System Storage N6240 Series These new systems replace the IBM N3600 and N6040 Series respectively. GA date is scheduled for January 28, 2011 (N6240) and February 25, 2011(N6210). Here is the slide deck that is published with the release.
